2.5gm answer ....2/18x22.5
Answer:
C. the layer at the bottom of the glass
Explanation:
The liquid with the higher density will be found at the bottom of the glass because is the heaviest of all. The liquids which have a lower density than the liquid at the bottom of the glass will be found at the top of the glass. We assume that the liquids are not soluble in each other because otherwise they will be mixed.
Explanation:
Relation between density, height, and surface tension is as follows.
The given data is as follows.
Density, (
) = 998.2 
g = 9.807 m/s
h = 4.96 cm = 
(as 1 m = 100 cm)
r = 0.3 mm = 
(as 1 m = 10000 mm)
Therefore, putting the given values into the above formula and calculate the surface tension as follows.
= 
= 
or, = 
Thus, we can conclude that value of surface tension is .
